243848 ÷ 3 
We want to figure out the number of times 243848 can be divided by 3.

Step 1:
If we divide 2 by 3, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 3

Step 2:
The number 3 fits into 24 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 24 from 24 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 3

Step 3:
If we divide 3 by 3, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
Subtract 3 from 3 to get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

Step 4:
If we divide 8 by 3, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 812.0
The remainder is 2 after subtracting 6 from 8.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 3

On to step 5:
24 divided by 3 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 8128.0
The remainder is 0 after subtracting 24 from 24.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 3

Moving on to step 6:
When dividing 8 by 3, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 81282.0
Deduct 6 from 8 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
20 divided by 3 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 81282.6
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
3 goes into 20 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 81282.66
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 81282.66, with a leftover of 0.002.
